Application filed May 3, 1923.

To a]! whom. it may concern.-

Be it known that 1, WILLIAM H. RiHL, a citizen of the United States, residing in Philadelphia. Pennsylvania, have invented certain Improvements in Driers, of which the following is a specification.

T he object of my invention is to construct a machine for drying rugs, and similar articles, on frames that are located in a horizontal position in the machine in order that all portions of the articles being dried will be subjected to the air in circulation.

In the accompanying drawings:

Fig. 1 is a side elevation illustrating my improved rug drying machine;

Fig. 2 is a plan view;

Fig. 3 is an end view;

Fig. a is a transverse sectional View showing the door construction in detail; and

Fig. 5 is a plan view of one of the frames.

Referring to the drawings, 1 is the casing, in which is a drying chamber 2. While the drying chamber extends from side to side of the machine. it stops short of each end of the machine, as indicated by the frames 4, so as to form circulating chambers 5 and 6. In the drying chamber is a series of supports 3 for the frames upon which the rugs, or similar articles, to be dried are secured.

In. order to circulate the air in the drying chamber properly, fans 7 and 8 are provided, which are located in the chambers 5 and (3 respectively. These fans are staggered, one fan being opposite one-half of the drying chamber and the other fan being opposite the other half of the drying chamber. The fans are located in the partitions 9 and 10. respectively. Each fan is mounted on a shaft 12 driven from a power shaft 30.

In. the chambers 5 and 6 are heating coils '11 and 11, respectively, which may be of any of the ordinary types so as to heat the air in circulation. These coils are located between the partitions 9 and 10 and the ends of the machine.

13 designates an air inlet opening communicating with the chamber 6. 14 designates an air inlet opening communicating with the chamber 5. Both of these openings communicate with their respective chambers at the side opposite the fans so that fresh air will be admitted to the air in circulation immediately after it leaves the fans. Communicating with the upper portion of each DRIER.

chamber 5 and 6 are exhaust fines 15 and 16, respectively. These exhaust fines communicate with the chambers back of the fans as illustrated in Fig. The flues 15 and 16 communicate with a fine 17, in which. is an exhaust fan 18 mounted on a shaft 19 driven from the shaft 30. Each support 3 is made of angle iron in the present instance. 7 V

In order to allow the frames 31, Fig. 5. to move freely into and out of the drying chamber, rollers 20 are provided, which are mounted in bearings 21 that project slightly above the guides. Movable rollers 22 are also provided. These rollers have trunnions that travel on the guides in a space 23. The traveling rollers support the frames while passing from one main'roller 20" to another. One end of the drying chamber is closed and at the closed end is a bumper bar 24 supported by springs 25, which cushion the frames as they are pushed into the drying chamber.

A door 26 is provided for each section of the drying chamber. These doors are arranged so as to swing down to allow a frame to be moved into and out of the section.

The frames 31 may be made as illustrated in Fig. 5, i. e., retangular in shape with one or more cross bars 27 and longitudinal bars 28. These bars are spaced according to the size of the rugs, or other fabric, be ing dried.

The central tier of rollers 20 act as a longitudinal partition to separate the two portions of the drying chamber (Fig. 1), so that air flowing in one direction in the drying chamber will not interfere with the air flowing in the opposite direction.

The operation is as follows: The rugs are stretched on the frames and are secured by tacks, or other fastenings, after which they are pushed into the drying chamber and the doors 26 are closed. Power is then applied and the fans circulate the air above and below the stretched rugs. The air, as it circulates, is heated to the proper degree. Fresh air is admitted, which takes the place of the damp air that is exhausted through the fines 15 and 16.

By this construction, all portions of the rugs are subjected to the air in circulation,

consequently, the rugs are dried uniformly.

I claim:

1. The combination of a casing; a drying compartment therein having a series of supports; frames on which rugs, or similar articles, to be dried are secured, said frames being located in the drying chamber in a horizontal position and one above another; circulating chambers at each end of the machine beyond the drying chamber; a fan in each circulating chamber, one fan being located at one side in one circulating chamber and another fan being located on the opposite side of the other circulating chamber so that the air Will be drawn through one side of the drying chamber in one direction and through the other side of the drying chamber in the opposite direction; and means for heating the" air in circulation.

2. The combination in a drying machine, of a casing; a drying chamber having a series of supports located one above another, said drying chamber extending from one side of the machine to the other and closed at one side and having doors at the opposite side; a series of frames on Which the rugs, or similar articles, to be dried are secured; circulating chambers at each end of the machine beyond the drying chamber; a circulating fan in each chamber; means for heating air located in each chamber; air inlets communicating with said chambers; exhaust pipes also communicating with the chambers; and an exhaust fan for drawing damp air from the drying chamber.

3. The combination in a drier, of a casing having a drying chamber therein and end circulating chambers; means for circulating air in the casing; a series of supports at each side of the drying chamber, one end of the drying chamber being closed; a bumper bar at the closed end of the drying chamber on Which the rugs, or similar articles, to be dried, are stretched, said bumper bar being located in the path of the frames as they are placed in position in the drier; and doors at the opposite side of the casing for closing the several sections of the drying chamber.-

4. The combination of a casing having a drying chamber therein extending from side toside thereof; means for circulating air in opposite directions in said drying chamber; a series of supports'for the frames on Which rugs, or similar articles, to be dried are placed; a series of fixed rollers mounted on each support; and a series of intermediate rollers arranged to travel on the supports as the frames are pushed into position, said intermediate rollers carrying the frames from one fixed roller to another.

5, The combination in a drier for rugs and similar articles, of a casing; a drying chamber having a series of supports located one above another; frames on Which the articles are secured, said frames being placed in the drying chamber in a horizontal position; circulating chambers at each end of the machine beyond the drying chamber; and fans for circulating the air, said fans causing air to flow in one direction through one-half of the drying chamber and to fioW in the opposite direction through the other half of the drying chamber.

'6, The combination in a drier, of a casing; a drying chamber having tiers; of rollers spaced apart for supporting the frames that carry the articles to be dried, the central tier of rollers acting as a partition separating one portion of the drying chamber from the other portion; and means for circulating air in one'direction in one portion of the drying chamber and in the opposite direction in the other portion of said chamber.
